sup-sync - sychronize the Sup index with message sources
sup-sync [options] source ...
Synchronizes the Sup index with one or more message sources by adding messages, deleting
messages, or changing message state in the index as appropriate.
"Message state" means read/unread, archived/inbox, starred/unstarred, and all user-defined
labels on each message.
"Default source state" refers to any state that a source itself has keeps about a message.
Sup-sync uses this information when adding a new message to the index. The source state
is typically limited to read/unread, archived/inbox status and a single label based on the
source name. Messages using the default source state are placed in the inbox (i.e. not
archived) and unstarred.
If no sources are given, sync from all usual sources. Supported source URI schemes can be
seen by running "sup-add --help".
MESSAGE STATE OPTIONS
--asis If the message is already in the index, preserve its state. Otherwise, use default
source state (default)
Restore message state from a dump file created with sup-dump. If a message is not
in this dumpfile, act as --asis
Discard any message state in the index and use the default source state.
-x, - When using the default source state, mark messages as archived.
When using the default source state, mark messages as read.
When using the default source state, also apply these user-defined labels (a
comma-separated list) (default)
Print message ids as they're processed.
As the final operation, optimize the index.
Scan over all sources.
Don't actually modify the index. Probably only useful with --verbose.
